react-sweet-state/lib/esm/context.js

Global + local state combining the best of Redux and Context API

import React from 'react';
import { defaultRegistry } from './store'; // Provide static calculateChangedBit to opt-out from context updates
// as we use our own subscription model

export const Context = /*#__PURE__*/React.createContext({
  globalRegistry: defaultRegistry,
  retrieveStore: Store => defaultRegistry.getStore(Store)
}, () => 0);
